2 Claims. (01. 61-53) ruption to the work.

The present invention splice clamps. An object of the present invention relates to relates to bearing pile Ifrigidly securing the ends of adjoining piling sec tions together with a minimum of delay and inter- A further object is to provide a clamp which can be quickly applied to the piling sections during the driving operation inorder to rigidly connect one piling section to another.

Other objects and advantages will "become apparent as thedescription proceeds and reference is made to the accompanying drawing, in which:

Figurel is a detailed elevation, showing the clampapplied to adjoining piling sections;

,Figure 2is a. section on lineIL-II of Figure 1; t

and

Figure 3 is an enlarged detailed section online III-III of Figure l.

In the drawing, the numerals 2 and 3 represent piling sections of any conventional design, the illustration being shown as of H or I-shaped cross-section. .After the piling section; 3 has been driven into theground until its upper portion approaches the ground line and it becomes necessary to position andalign another piling section thereon, such can be done with a minimum of delay and interruption to the work.

For effecting the rigid connection of the two piling sections, the clamping device of the present of a member having a c-shaped cross-section and comprises a main bodyportion 4 and flanges 5 and 6 extending from the main body in the same direction and spaced from each other to I-beam piling sections.

The flange5 of the clamp is tapped to provide a plurality of vertically aligned openings through i which screws 8 are adapted to pass. The opposite flange 6, of the clamp, is provided with shallowdepressions 9 in alignment with the vertically spacedapertures formed in the flange 5.

When it becomes necessary to add a piling section, the clamp is secured to the flanges of the structural member 3, after which the set screws 8' are tightened up so thatthey bear againstthe flanges I of the structural member, and, upon. additionaltightening upon said setscrews 8, they a bite intoone surface of said flanges'l and, as a resultythe, flanges 1 are forced slightly into the shallow depressions 9 opposite the point of engagement of the screw with said flanges'l, as

, sections being joined is made secure.

clearly shown in the enlarged detailed sectional view of Figure 3,so that the grip of the clamp upon the structural member is secure. The upper piling section 2 is then positioned so that the flanges 1 enter the grooves or channelways formed by the two flanges 5 and E of said clamp and said piling section 2 isgradually lowered into position to insure a firm seating upon the abutting end of the piling v section 3 after which, the set ends of the piling sections 2 and 3 is eliminated.

It is not necessary to initially provide drill holes in the piling sections or experience the usual delays caused in securing the clamps to the piling sections by the usual method of welding. The

clamp of the present invention provides a continuous pressure due to the spring-like action so that the set screws remain in tightengagement a with the flanges of the structural members 2 and- 3, and do not become loosened under the, action of the pile hammer during the driving operation.

While I have shown and described a specific embodimentof the invention, it will be understood that I do not wish to be limited exactly thereto, since various modifications may be made Without departing from the scope of the invention, as defined in the following claims. I claim:

1. In a bearing pile construction including two or more H or ;I- shaped beam members, splice clamps positioned on the ends of the adjoining beam members for securing said beam members in alignment so that drivingof the bearing pile can proceed with a minimum of delay, said clamps, 0

each comprising a main body portion having spaced flanges extending in the same direction to provide a channelway or groove of a width sufiicient to accommodate the flanges of said H or I-shaped beam members, one of said flanges provided with vertically aligned spaced apertures, depressions formed on the other flange in alignment with said spaced apertures and a threaded bolt extending through said apertures and conta'cting the flanges of said beam members so that tightening up of. the threaded bolt will .force the g metal of the flanges of said beam members slightly. into said depressions whereby the grip of the splice clamp and the threaded bolts on the piling 2. In a bearing pile construction including two or more H or' I-shaped beam members, splice clamps positioned on the ends of the adjoining beam members for securing said beam members in alignment so that a driving of the bearing .pile can proceed with a minimum of delay said clamps each comprising a main body portion having spaced flanges extending in the same direction to provide a channelway or groove of a width 10 sufficient to accommodate the flanges of said H or I-shaped beam members, one of said flanges provided with vertically aligned spaced apertures and a threaded bolt extending through said apertures and contacting the flanges of said beam members so that tightening up of the threaded bolt will force the end of said boltinto the metal of the flanges of said beam members, whereby the grip of the splice clamp and the threaded bolts on the piling sections being joined is made secure.
